FLUE BLOWER.

Application led November 16, 1921. Serial No. 515,619.

To all 'whom t may concern.' v Be it known that we, ,ROBERT E; JACKSONand 3DWIN M. JENKINS, citizens of the United States, residingatPrinceton, in the county of Mercer and State of West Virginia, haveinvented certain new and useful Improvements in Flue Blowers, of whichthe i'ollowing is a specication. l

This invention'relates to improvements in flue blowers and moreparticularly to a de# Yvice, adapted to be attached to a boiler wherebyany selected flue may be cleaned as desired.

In a prior Patent No. 1,416,209, granted May 16, 1922, we have disclosedandclainied a iiue blower in which a rotatable support is arrangedwithin the lire box and a flue cleaning device is transversely mountedon said support and adapted to'be alined with the end of the liue to becleaned. In the present invention, we have provided a flue cleaner inwhich movable parts within the boiler are eliminated. A plurality ofheaders are arranged transversely of the smoke box mounted on suitablesupports, a header being provided for each vhorizontal row of tlues. Theheaders are provided with a plurality of lead lines or pipes arrangedtherein communicating with the individual liues of the row. Each of theheaders is connected to a suitable supply of compressed air, steam, orother compressed fluid and means are provided for feeding the fluid toany selected pipe within' the header.

`The valve mechanism whereby any desired connecting pipe is connected tothe sourceof supply is arranged on the outside of the boiler and isreadily accessib-le at all times.

In the accompanying drawings, We vhave shown one embodiment of theinvention. In this showing:

Figure 1 is alongitudinal sectional View of a portion of a boilershowing the invention applied,

Figure 2 is a transverse vertical sectional view on line 2-2 of Figure1,

Figure 3 is ay side elevation of a portion ofV the'boiler showing thevalve arrangement, A

Figure 4 is a detail view of a portion ot the header,

Figure l5- is an end elevation thereof,v Figure 6 is a detail view ofthe header valve casing, parts being shown in xsection, Figure 7 is aplan View ofone ot the headers, f

'Figure y8 is a sectional view on line 8 8 of Figure 6 and, Figure 9 isa detail viewfof the inner end ot one of the connecting pipes.

Referring to the drawings, .the'reterence numeral designates the smokebox ot a boiler and 2 the front flue sheet. Theboiler disclosed 1s thelocomotive type', but the in'- `vention may be employed with any ltypeof lire tube boiler. A plurality ot' lues 3 eX- tend Vthrough the fluesheet in the usual manner. p

'Ilie'lu'e blower forming the subject matterotv the invention consistsof a plurality of headers 4l arrz-ulged transversely` oil the smoke boxand in horizontalalinement with each row or" lines. One end of theheader is provided with grooves 5 for ythe reception oj brackets 6secured to the wall ot the boiler. The opposite end of theheader eX-tends through an opening inthe opposite side of the boiler and` issupported byA means oi' suitable brackets. Asv shown, ths ,end of theheader is enlarged, as at 7, the body portion and the enlargement beingprovided with flanges 8 adapted to receive boltsQ by ineansot vwhich thesections are held tothe stem is square, asat18. A plate 19 is arrangedon the valve casing, the platebeing provided with a circular openingfor'the passageA of the circular portion 17 of the valve stein. This`plate is provided witha plurality of notches 20, arranged about itsperiphery. A' handle 21 is arranged on the squared portion ofthe valvestem and retained in position by means ot' a pin 22. The handle extendsbeyond the plate 19 and is provided with a plunger 23 arranged in arecess and normally retained in position by means of a spring 24.

A plurality or connecting pipes 25- are arranged within the header, thenumber of connecting pipes in each header corresponding to the number ofllues in the horizontal row. The ends of these pipes within the enlargedportion 7 are arranged concentrically in alinement with the opening 14in the valve. The connecting pipes 25 extend longitudinally of theheader to a point in alinement with the l'lues to which they are to beconnected and are then olset, as at 26, and extend through the front ofthe header. The pipes or passages 25 are provided with lead pipes 27extending into the end of the tlues (see Figure l). These lead pipes areprovided with flared ends 28, the flared portion extending downwardly todirect the blast of steam or air against the lower wall othe Hue andinsure perfect distribution ot' the. cleaning fluid within the tlue.

The operation of the device is as follows:

When a tine is to be cleaned, the valve is turned to connect the valvecasing with the proper pipe or passage 25. Steam, compressed air orother suitable fluid is introduced into the valve casing through a pipe29 which may be provided with a suitable valve (not shown) whereby thesupply of fluid to the valve casing may be controlled. The position ofthe opening in the disk valve 13 may be determined by suitable indiciaarranged on the plate 19 and disposed adjacent the notches 20. The platewill be provided with one more notch than the number of flues in eachrow, and one position of the handle 21 will indicate that the valveopening 14 is out of alinement with the pipes or passages 25, the otherpositions indicating that the valve opening is in alinement with one ofthe passages to direct fluid to a. given flue. The iuid passing throughthe opening in the valve and the pipe or passage 25 is directed to thelead pipe 27 thence to the interior of the flue.

lt is to be understood that the form of our invention herewith shown anddescribed is to be taken as a preferred example of the same, and thatvarious changes in the shape, size, and arrangement of parts may beresorted to without departing from the spirit of the invention or thescope of the subjoined claims.

Having thus described our invention, we claim:
